The process which is performed in the apparatus that is the subject of the iresent application is clearly set forth in said lebersat; patent and further description thereof at the present time is deemed unnecessary. An object of the present invention is to construct an apparatus with a plurality of drums for polishing silver articles of different sizes, that is with a relatively large drum wherein to polish relatively large pieces of silver, such as colfee-pots, platters or the like and a relatively small drum wherein to pol ish relatively small pieces of silver, such as knives, forks, spoons, salt-cellars, small ramekin dishes and the like.

A further object of the invention is to construct the polishing apparatus with a pinrality of drums and to drive them in such a manner that either one or both of the drums can be operated as desired from a single source of power, such as from a continuously rotating common driving shaft.

As showing a specific embodiment of the invention reference is made to the drawings forming a part of this specification, inwhich drawings- Figure 1 is a side view of a complete apparatus.

Fig. 2 is a longitudinal sectional view showing the gear construction at one end of the machine. 7

Fig. :3 is a transverse sectional view taken as onthe plane indicated by the broken line 33 of Fig. 2 looking in the direction of the arrows.

of power, to wit, the driving pulley of the motor.

Fig. 5 shows the machine in plan.

Like parts are designated by the same reference characters in the specification and also onthe drawings, and it will be understood that the parts shown in Fig. 4 are the same as the parts shown in the other figures, even though they are illustrated in Fig. 4 moreor less diagrammatically.

The apparatus comprises a trough or trough construction 1 having legs 2 which may be considered as constituting a support.- ing frainefor the trough. At one end of the trough, to wit, the left-hand end, there is located a relatively small drum 3 which is carried on a transversely extending, drum shaft l. This shaft is supported by any suitable hearing, as 5, on the trough. A larger drum 6 is carried on a longitudinally extending drum shaft 7. This shaft is supported by any suitable bearings, as 8 and 9. that are on or carried by the trough. At the righthand end of the trough there is secured a casing 10 within which the major portion of the gear construction for driving the drums is located. Within this casing there is carried by bearings 11 and 12 a longitudinally extending common driving shaft 13. This shaft 13 has been referred to as the common driving shaft since it can continuously rotate;

and it is fromthis shaft that either one or both ofthe drums can be intermittently driven at will as will hereinafter appear. This common driving shaft 13 has secured to it a worm-wheel 1% that is in mesh with a worm 15 located within the casing' and which is upon the worm-shaft 16 that extends to the exterior of the casing. vAs this casing preferably contains lubricating material, such as oil or grease, it is made liquid-tight and the wornrshaft 16 extends through a packing 17 constructed so as to prevent the escape of the lubricating material. A thrust"- bearing 18 is provided to take care of the thrust and wear resulting from the driving of the worm-wheel l t by means of the worm 15. The worm-shaft 16 has secured to it a pulley 19 located on the exterior of the casing" and this pulley is driven by a belt-2O from a pulley 21 driven by a motor 22 carried upon a bracket 23 secured to the trough 1 by being connected to the supporting legs 2 Patented Nov. 9, 1920.

for the trough. The worm-shaft 16 may be referred to as a power-transmission shaft since thisnomenclature serves as a convenient way of identifying a shaft that performs the function of transmitting power that it receives from the motor 12 on the one hand to either or both of the drums 3, 6 on the other hand, dependent upon whether clutches corresponding to the drums are closed and which clutches are in a power-transmission train or gearing between said power-transmission shaft 16 on the one hand and the drums on the other hand. This motor 22 is located at the left-hand end of the trough directly below the portion in which the drum 3 is located.

It will be noted that the common driving shaft 13 is continuously rotated from the motor while the apparatus is being used. The bearing 9 for the longitudinally extending drum shaft 7 is, as a matter of fact, provided on the casing 10 and the shaft 7 extends through this bearing into the interior of the casing and to this extending end of the shaft there is secured by means of a pin or key 24 a gear 25. This gear 25 is in mesh with a pinion 26 that is slidably mounted upon the common driving shaft 13. Thecasing 10 has a bracket 27 which provides a fulcrum at 28 for a lever 29 having a forked end 30 that engages a grooved portion 31 on the pinion 26. When the parts occupy the position shown in Fig. 2 a clutch member 32 on the pinion 26 engages a companion clutch 33 on theworm-wheei 1a. and the gear or pinion 26 is held in this position by the lever 29, due to a locking mechanism 34 which is carried by the lever and which on ges a notched portion 35 on the bracket 2%. and 33 engage each other the driving is from the worm-wheel 14 through the clutch members to the pinion 26, the gear 25 to the shaft 7 upon which it is carried and to which there is secured the'drum G whereby as the shaft 7 turns the drum 6 revolves therewith. The worm-wheel 14 may be considered as a part of the common driving shaft 13 when performing this function. The construction just referred to may be considered as a reducing gear mechanism comprising a clutch between the common driving shaft 13 and the shaft 7 that carries and drives the drum 6.

The gearing construction between the shaft 13 and the shaft 7 constitutes means for positively transmitting power from the V shaft 13 to shaft 7 when the clutch that is comprised in said power-transmitting means is closed and hence said means may be referred to as a clutch-controlled, positive power-transmitting means between the common driving shaft 13 and the large drum shaft 7.

The casing 10 also has a bearing 36 which ing common driving shaft 13.

of gear1ng-and 1t Wlll be noted that a When the clutch members 32, d

pulley 42 which is revoluble relative to the transversely extending drum shaft 1, but which can be coupled by means of a clutch 43' to said shaft to drive the latter. This clutch is under the control of the lever 44.

The construction previously described may be referred to as a clutch-controlled powertransmitting means between the common driving shaft 13 and the small drum shaft 4:.

The construction described as a means for transmitting the power from the common,

driving shaft to the transversely extending drum shaft 4t may also be broadly considered as a gearing comprising a clutch construction or as a belt and pulley construction comprising a clutch whereby the shaft 4 and drum carried thereby can be rotated at will from the continuously rotat- This train pulley and belt construction may be broadly considered as gearingis a reducing gear ing but it does not reduce the speed as much as does the reducing gearing between the common driving shaft and the larger drum; in other words, the reducing gearing construction between the common shaft on the one hand and the drums on the other is such that the large drum makes a less number of revolutions per minute than does the small rum.

From the construction which has just been described it will be noted that by merely closing or opening the clutch 43 the small drum 3 can be rotated and stopped rotating at will while the common driving shaft 13 is being rotated and, as above pointed out, by closing and opening the clutch which comprises the members 32 and 33 the large drum can be rotated or stopped rotating, at

will, while the common driving shaft 13 is being rotated.

The trough 1 may be formed so as to include two compartments, or there may be only a common compartment into which both of the rotating drums extend. The means for withdrawing any water or liquids from the trough is designated by 45. The drums are provided, as usual, with the main or body part 46 and a removable or cover part 47. As, however, the drums employed may be of any suitable construction the details thereof are not herein described.

The improvements herein set forth are not limited to theprecise construction and arrangement shown and described for they may be embodied in various forms and modifications without departing from the spirit and scope of the invention.
